I found this badge query.
SELECT p.user_id, min(p.created_at) granted_at, MIN(p.id) post_id
FROM badge_posts p
JOIN topics t ON t.id = p.topic_id
WHERE category_id = (
SELECT id FROM categories WHERE name ilike 'Technology'
) AND p.post_number = 1
AND views >= 10
and (:backfill OR ( p.id IN (:post_ids) ))
GROUP BY p.user_id
Note this is not mine. Here is the OP.
